Introduction to FAA Obstruction Marking and Lighting Standards
The Federal Aviation Administration (FAA) obstruction marking and lighting regulations form the backbone of aviation safety in U.S. airspace. These critical standards ensure all potential aerial hazards - from skyscrapers to wind turbines - are properly identified to prevent collisions. As urban development continues vertically and renewable energy projects expand, compliance with FAA obstruction marking and lighting requirements has never been more vital.
The Evolution of FAA Obstruction Marking and Lighting Guidelines
Historical Context
The FAA obstruction marking and lighting standards trace their origins to the Air Commerce Act of 1926, with significant updates occurring:
1970s: Introduction of specific light intensity categories
1990s: Implementation of LED technology standards
2010s: Adoption of new wind turbine marking requirements
Current Regulatory Framework
The FAA obstruction marking and lighting requirements are primarily detailed in:
Advisory Circular (AC) 70/7460-1L
14 CFR Part 77
FAA Order JO 7400.2L
